In twenty years you will look back, and very little will be the same, you'd give anything to go back in time, and be this age again. To be as healthy as you are right now, to be able to move your body at your will, you'd give anything to turn the clock, how you'll wish that time stood still. So take a moment to be grateful, for those little things we take for granted everyday, enjoy the present, in all that you are, for it won't always be this way.
